FuturePundit: Illumina Full Genome Sequencing Costs Below $20k

Update: To the extent that the US FDA and like-minded agencies reduce the availability of DNA sequencing services they slow the rate of technological advance. Fewer people paying to get their DNA sequenced means less revenue to use to generate future generation sequencing devices. This delays the day various benefits of sequencing will be realized. We will be less healthy than we otherwise would be absent regulatory meddling. I am looking forward to the day when full genome sequencing becomes affordable. If millions of people can get their DNA sequenced then the meaning of genetic variants [more...]

Science News for Kids: Feature: Scientist Profile: Wally Gilbert

You've won a Lasker Award and a Nobel Prize for your research on sequencing DNA, basically figuring out the order of the letters in this very long word. How does that method work? Fred Sanger in England invented one method, and I invented another with my collaborator, Allan Maxam. The very first piece of DNA we deciphered was only 20 groups long. It took us two years to work out the order of those groups. A typical gene in our body is some ten thousand groups long, so you couldn't possibly work out the entire order of groups for a gene. Then suddenly we discovered a simple way of doing it. It [more...]

Between the Covers: New to Our Shelves

In this explosive new book, Sam Harris tears down the wall between scientific facts and human values, arguing that most people are simply mistaken about the relationship between morality and the rest of human knowledge. Harris urges us to think about morality in terms of human and animal well-being, viewing the experiences of conscious creatures as peaks and valleys on a "moral landscape." Because there are definite facts to be known about where we fall on this landscape, Harris foresees a time when science will no longer limit itself to merely describing what people do in the name of [more...]

SpringerProtocols: Abstract: The State-of-the-Art of Chromatin ...

The biological significance of interactions of nuclear proteins with DNA in the context of gene expression, cell differentiation, or disease has immensely been enhanced by the advent of chromatin immunoprecipitation (ChIP). ChIP is a technique whereby a protein of interest is selectively immunoprecipitated from a chromatin preparation to determine the DNA sequences associated with it. ChIP has been widely used to map the localization of post-translationally modified histones, histone variants, transcription factors, or chromatin-modifying enzymes on the genome or on a given locus.

Graphene could revolutionize DNA sequencing - physicsworld.com

By feeding individual strands of DNA through nanometre-sized holes, researchers in the Netherlands say they have proved the principle of a revolutionary new DNA sequencing technique. The breakthrough is part of a worldwide race to develop fast and low-cost strategies to analyse these codes that underpin the chemistry of life. The genetic profile – or "genome" – of an organism is determined by recording the full sequence of acid base pairs that make up its DNA. In 2003, the Human Genome Project made history by determining the entire human genetic code – 3 billion DNA base pairs that took [more...]

Crime Lab DNA Databases Under the Microscope

Researchers in the field of DNA forensics are calling for the FBI to improve the quality of its sizable genetic database by letting them look under the hood. As Osagie Obasogie explains, reviews of a handful of state crime lab DNA databases have revealed anomalies that might not make prosecutors’ claims that a crime-scene sample matching a profile in the database is “slam dunk” evidence. Genetic information is a powerful law enforcement tool—both for catching criminals and for exonerating the innocent, but both uses require robust, accurate science.

Steve Talbott's genomic dynamite (What's Wrong with the World)

How could we hold our heads up with high-browed, post simian dignity when, as the New Scientist reported in 2003, “chimps are human”? If the DNA of the two species is nearly the same, and if, as most everyone seemed to believe, DNA is destiny, what remained to make us special? Such was the fretting on the human side, anyway. To be truthful, the chimps didn’t seem much interested. And their disinterest, it turns out, was far more fitting than our angst. The bulk of the essay is given to careful explication of the inadequacies of the long-regnant genomic model to explain gene expression. [more...]

In the Darwinist repertoire, a standard response to evidence of design in the genome is to point to the existence of "junk DNA." What is it doing there, if purposeful design really is detectable in the history of life's development? Of course this assumes that the "junk" really is junk. That assumption has been cast increasingly into doubt. New research just out in the journal Nature Genetics finds evidence that genetic elements previously thought of as rubbish are anything but that. The research describes tiny strands of RNA, previously thought to be junk, that now turn out to play a role in [more...]
